Multiple Tech and Science Articles Circulated

Six unrelated technical and science articles appeared on Hacker News July 20–23: malloc behavior, Mac security scanning AI, Emacs development setup, Bun's Zig runtime, MCP security vulnerabilities, and quantum gravity research.

Comparison of Malloc() Algorithms

Another boring night at work. Looks like we'll have plenty of time for C drills. void* me = malloc(sizeof(ego)); me = NULL;

🔍 Deep dive on the changes: • Tail compaction: In-place chunk updates in contiguous frames previously read the full remaining tail into RAM (malloc(tail_nbytes)). The new frame_move_range mechanism b

SkillBloat: Token Amplification Attacks via Skill Injection in LLM Coding Agents

21929v1 Announce Type: new Abstract: Agent skills extend coding agents with task-specific instructions, scripts, and resources, but they also create a trusted instruction channel that can be abused beyond conventional security attacks. This paper studies token amplification through skill injection: an economic resource-abuse threat in which a malicious skill causes an agent to consume substantially more tokens than needed for normal task execution.
